SPECIFICATION forming part of Letters Patent No. 429,357, dated June 3, 1890.

Application filed February 25, 1890.-' Serial No. 341,724. (No model.)

To all whom it may concern,.-

Be it known that LRANDOLPH MoBEE, a citizen of the United States, residing at Vashington, in the District of Columbia, have invented certain new and useful Improvements in Pipe-Han gers; and I do declare the following to be a full, clear, and eXact description. of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved device whereby water or other pipes may be hung or suspended from ceilings or may be secured in a vertical orinclined position at a suitable distance from upright Walls.

It is the object of my invention to provide a simple and inexpensive device for this purpose which may be readily employed in a variety of situations, which is adapted to carry a single pipe4 or a plurality of pipes of various sizes, which is adjustable to meet the various circumstances under which it may be used, and which can be readily but firmly attached either to a solid beam or to the botpom of a floor or to the laths behind the plas- My invention comprises, essentially, a screwthreaded wall-plate and a correspondinglythreadednipple-plate constructedand adapted to be combined and employed as hereinafter more particularly set forth.

In order to make my invention more clearly understood, I have shown in the accompanying drawings means for` carrying thesame into practical effect.

In said drawings, Figure l is a vertical sectional view of a pipe-hanger embodying my invention and shown as applied to the support of two pipes and as attached to a solid beam, cert-ain additional attachments, which may or may not be employed, being indicated by dotted lines. Fig. 2 is a perspective vieW of a nipple and transverse plate, the same constituting a part of, but shown as detached from, the complete construction shown in Fig.' l. Fig. 3 is a vertical sectional view of what may be termed the nipple or hanger7 plate detached from the Wall-plate and provided with pipe-rests separate from or detachable from the plate. Fig. 4 is a perspective sectional vicw of amodiiied form of pipe-hanger.

wall-plate, provided with a screw-threaded aperture a., in which is adapted to t the correspondingly-threaded nipple b, carrying the transverse plate B. The said nipple is provided with a central conical socket b', having at its upper end a perforation h2, through which may be passed a screw C, to secure the whole device to a beam, as indicated in Fig. l. Where a solid support like a beam can be obtained, this central screw is aA sufliept nieans'of support for the entireliangerbut where a thin partition or a plastered ceiling forms the support I employ small screws of a sufficient number, as indicated at C', which pass through suitable apertures formed in the base-Hangs A ot' the Wall-plate.

` The transverse plate B, carried by the nipple, is provided with one or more pipe-rests D, which may be formed with the plate, as indicated in Figs. 1 and 2, or may be separate and attachable thereto, as indicated in Figs. 3 and 4, and in the case of the central pipe-rest, in Fig. l. When said rests D are separate from the transverse plate B, they are attached thereto after having been passed around the pipes P by suitable means, such as screw-bolts s and nuts s'. In order to enable the same nipple-plate to be employed for 'various diameters of pipe, it is longitudinally slotted, as shown at b3, thus providing for the attachment of straps of different lengths. Such slots may also be provided in the form of plate shown in Figs. l and 2, wherein the rests D are integral with the plate, and the device is thus adapted for the attachment of an intermediate separate rest carrying a third pipe, as shown in dotted lines in Fig. l.

By extending the plate B, as indicated in Fig. 3 and in dotted lines in Fig. 6, a plurality of pipes may be carried by a series of separate rests D. It will be seen by considering the relations of the wall-plate, nipple-plate, and central screw C that, the nipple h having been in- IOO serted in the threaded opening e, and the screw C having been passed through the perforation b2 and engaged with the beam or other support, the plate B may be rotated in the proper direction to bring it to such distance from the wall or support as to meet the pipe or pipes to he supported. The screw C is then screwed down to a firm bearing in the socket Zr', and the wall and nipple plates will be rigidly secured in position. The pipe or pipes I) are then laid in the pipe-rests D, if the latter are of the form shown in Fig. 2. If the rests D are separate from the plate B, the former are passed around the pipes and secured to the transverse plate by theserews and bolts s s.

If it is desired to support the pipes in suoli position that gravity cannot be relied upon to keep them in place in pipe-rests of the open form shown in Fig. 2, I employ a plate E, (see Fig. 1,) provided with a central opening e, screwthreaded to correspond with the thread upon the nipple I), the ends of which plate, when it is screwed down upon the nipple, will engage the sides of the pipes opposite to the rests D. Such plate E is slotted at e to correspond with the slots in the plate B and admit of the attachment of a separate central pipe-rest.

In the construction shown in Fig. 7 a separate pipe-rest is pivotally secured to the plate I3 by a bolt running transversely of the pipe and indicated by the letter s2. This bolt passes through openings in the vertical ends D of the pipe-rest and through similar openings in depending lugs B', formed upon the plate B. The hanger is thus adapted to permit a swinging or longitudinal movement of the rest D to accommodate the expansion of steam or other hi ghly-heated pipes.

IIavin g thus described my invention, what I claim as new, and desire to secure by Let-- ters Patent, is

l. In a pipe-hanger, the combination, with a screw-threaded wal1-plate, of a correspondingly-threaded nipple having a socket and perforation for a fasteningscrew and a transverse plate having longitudinal slots, and a concave pipe-rest carried by said transverse plate, substantially as set forth.

2. In a pipe-hanger, the combination, with a screw-threaded wall-plate, of a correspondv ingly-threaded nipple having a socket and perforation for a fastening-screw and formed with a transverse plate having longitudinal slots and adapted to receive a concave strap or pipe-rest, substantially as set forth.

3. In a pipe-hanger, the combination, with a screw-threaded wall-plate, of a correspondingly-threaded nipple having a socket and perforation for a fastening-screw and formed with a transverse plate having longitudinal slots, and a concave pipe rest or rests fitting said plate, substantially as set forth.

4. In a pipe-hanger, the combination, with a wall-plate, of a separate transverse plate, said parts having the one an opening or recess and the other a projection or nipple litting such recess, a central fastening-screw, and a concave pipe-rest carried by the transverse plate, substantially as set forth.

5. In a pipe-hanger, the combination, with a wall-plate, of a separate transverse plate, said parts having the one an opening or recess and the other a projection or nipple f1tting such recess, means for secnrin g said plates together, and a con cave pipe-rest earried by the transverse plate, substantially as set forth.

In testimony whereof I affix my signature in the presence of two witnesses.

RANDOLPH MCBEIC.
